Was a gift to high school engineering student. I see her use it often. For reference, and it also comes in handy for opening boxes. A multi-functional tool. I think it is well made.

This basic low-tech gadget has been great for me with the tasks I've needed it for: most-routinely taking small measurements of 3" or less, as an alternative to keeping a bulky tape measure on my belt (or in my pocket), causing my pants to 'droop' and/or my shirt to become untucked. The square corners are of course functional for measuring purposes, but are a risk of pocket-wear, depening on how one stores it. I use my wallet, or keep it in a small stack of other things, in my shirt pocket.
I keep it in the included cardboard sleeve, and also in the included inner, clear-plastic sleeve. This is a bit 'fussy' trying to keep track of both the cardboard sleeve and the plastic sleeve, and trying to keep them 'nice'... in my routine tasks, I routinely have dealt with oil-covered metal, so gets a bit messy/problematic, especially when trying to put the card back in all the sleeves, lol.

It would be a useful improvement, to have a single, durable plastic sleeve,
of course only very slightly larger than the 'measuring-card' itself,
i.e. with rounded corners, to improve 'stowability'

Either way I like it and it has saved me the trouble of having to carry around a much bulkier tape measure.
